"I don't even know where to go with that one," Rosenbaum tells PEOPLE with a laugh on Thursday, when asked his thoughts on the topic. "It's a belief and we don't share it."

That said, the pair – who wed in December at the picturesque Langham hotel in Pasadena, Calif. – respect Lowe and Giudici's decision.

"Those are their own personal beliefs and we're not going to judge them," Rosenbaum says. "We do our thing, they do their thing."

Adds Hebert with a laugh: "More power to 'em! I admire people who can do that, you know what I mean? I'm not interested in it, but ... I think that shows a lot of strength."

But the newlyweds have something big in common with the newly engaged, aside from finding love on TV. Like Hebert and Rosenbaum, Lowe and Giudici plan to wed on air.

"If they've decided they've spent enough time with each other that they're ready to go ahead and get married, I would say definitely doing it the way that we did it on TV was amazing," Hebert says. "Everything about the whole wedding process was seamless and simple and beautiful."

Rosenbaum – who, alongside Hebert, recently teamed up with Valspar paint to help raise money for Habitat for Humanity – says he originally feared that filming their special day in front of cameras would make it "feel like a show and not a wedding."

Luckily, he says, "It felt like a wedding. Our friends and family and everyone was there. They were happy and feeling the love. We had nothing but a wonderful, positive experience."

Moving forward, the couple expect to have kids. "[I] want one kid and J.P. wants two kids, so we'll probably have two," Hebert shares. But they aren't in any rush.

"Ashley has to finish her dental residency, which will be a year away in June," explains Rosenbaum. "Once she's done with her residency and we figure out where she's going to work, then we'll start thinking about family. But it's not far off."
